Version 4.0.2

General

• A new panel has been added to the GUI. This panel displays the information previously shown as tool-tip information, but also includes additional information on units, default values or admissible parameter ranges.

Known Issues

• Visualization of results in QGIS requires manual modification of .xdmf file: change '<Xdmf Version="3.0">' to '<Xdmf Version="2.0">'.
• Model setup fails if there is a dot ‘.’ in the working directory path. For example: “MySimulations/Sim1.1/" does not work, while “MySimulations/Sim1_1/” works.
• Aborting a simulation using Ctrl+C can corrupt the HDF5 result file.
• Abort bottom may no work as intended, i.e. simulation does not stop.

Module BASEHPC

General

• For LINKED boundary conditions and the INTERNAL boundary condition hqrelation_internal, the inflow conditions at the downstream boundary can be controlled better by the user via the newly introduced tag type_downstream. Four options are available as downstream inflow conditions. For all options, the mass inflow flux is calculated based on outflow at upstream boundary as previously. The difference lies in the calculation of the momentum flux over the boundary (more information is provided in the documentation):
  • no_momentum: No momentum flux over the boundary.
  • froude_downstream: Momentum flux calculated based on Froude number in the elements of the downstream nodestring.
  • froude: Momentum flux calculated based on the Froude number specified via the parameter froude_number.
  • uniform: Momentum flux calculated based on uniform flow conditions for the slope specified via the parameter slope.

• With this new feature, the LINKED boundary condition zhydrograph_linked_kinE became obsolete and has been removed.

Bug fixes

• A bug during writing the .xdmf output file resulted in unresponsive behaviour when visualizing the results in ParaView or even errors in QGIS. This bug has been fixed for visualizing the results in ParaView. Since the QGIS mesh layer does not yet support XDMF Version 3.0 it is necessary to manual replace the line '<Xdmf Version="3.0">' at the top of the .xdmf output file by <Xdmf Version="2.0"> in order to load the simulation results onto the mesh layer.

Module BASEMD

Bug fixes - General

• Absolute file paths on BASEMD simulations resulted in errors. This has been fixed.
• A bugfix implemented in v4.0.1 resulted many parameters of the BASEMD module being mandatory. This has been reverted. Those parameters are again intialized in the background if not explicitly defined by the user, results in the same behaviour as not explicitly specifying them in BASEMENT version 2.8.2 and earlier.

Known Issues - BASEplane

• The upstream and downstream stringdefs of the inner boundary weir must be of the same length, otherwise mass might not be conserved.

Known Issues - BASEchain

• Fixed bed starts eroding if both suspended load and bed load transport are activated if the suspended load is below transport capacity.
• Van Rijn formula does not result in any sediment being transported (1D-model).

Note: Existing installations of BASEMENT version 3.0.1 (or earlier) are not automatically detected by the updated installer. Therefore, uninstall any previous version of BASEMENT e.g. using the link in the Start Menu before installing the newest version.
